If the distance between two objects is tripled, by what factor will the
gravitational force between them change?
1/(3^2) = ?
That's called using the inverse square law.
but what is the 3^2 for? If the 3 is for the distance being tripled...what about the exponent 2?
Oh nvm, you mean
F = 1/d^2
1/(3^2) = 1/9
Square the distance ratio and put it in the denominator
if the separation distance b/w two objects is tripled is increased by a factor of 3,then the force of gravitation is decreased by a factor of 6
